As a former lathe machinist, I often made female threads only with my lathe, this is really no big problem. All you need is a special lathe chisel for female threads.
Same here. I have a lathe, plus other machine tools, in my basement - use them as great relaxation tool!
I have cut internal threads, but only in fairly large diameter holes - 1/2" at least, for anything smaller I use taps.
Here's part of my basement. One of the challenges here is to make the part not look like it was made on a CNS mill.
I have some experience making parts that look old for some restoration projects.
